For years, the left has spun the debate over global warming in the starkest Manichean terms. Those who disagree with the scientific and policy orthodoxy have been maligned as greedy capitalists bent on raping the earth of its natural resources for cheap material gain; they have been cast as the benighted enemies of reason itself. Efforts to publicly challenge the science behind global warming have too often resulted in professional and political character assassination. To be skeptical about the fashionable scientific and policy platform aggressively advocated by the mainstream media and self-indulgently championed by the Hollywood elite is nothing less than an “assault on reason,” to borrow Al Gore’s hyperbolic rhetoric. In predictably technocratic fashion, the left has claimed its own peculiar position as the only scientifically legitimate one - everything else reduces to craven interest, manifest dishonesty, or antiquarian faith.

However, maintaining this self-serving narrative just got a lot harder. In the last few days, the cause of climate alarmism took a big hit when more than a thousand e-mails exchanged by scientists at the University of East Anglia’s Climactic Research Unit (CRU) suddenly surfaced online. These e-mails were published by the computer hackers who apparently stole them, a crime that should be investigated and prosecuted. But notwithstanding the e-mails’ route to publication, their actual content is extraordinary. These behind-the-scenes discussions among leading global-warming exponents are remarkable both in their candor and in their sheer contempt for scientific objectivity. There can be little doubt after even a casual perusal that the scientific case for global warming and the policy that springs from it are based upon a volatile combination of political ideology, unapologetic mendacity, and simmering contempt for even the best-intentioned disagreement. Especially in anticipation of the major climate summit taking place in Copenhagen next month, the significance of this explosive disclosure is hard to underestimate. According to climatologist Patrick J. Michaels, “This is not a smoking gun; this is a mushroom cloud.”

» How much "Man Made" CO2 Is In The Earth's Atmosphere?
I think ALL of the CO2 in the Earth's Atmosphere is from man.
I'm not sure how much "Man Made" CO2 is in the Earth's Atmosphere.
There is .04% CO2 in the Earth's Atmosphere and of that "Man" has added an extra 4% (1 part in 62,500)
